Background: This research was designed to establish the posteroanterior (PA) radiograph norms for Iranian adult population. It also aims to distinguish any possible differences between genders. Finally, it will compare these norms with the norms of other populations.

Materials & Method: The population enrolled in the study was 60 Iranians aged between 18 and 45 years. Those included in the study satisfied the most important inclusion criteria: (i) Iranian origin (ii) bilateral Angle class I molar and canine relationship (iii) no history of orthodontic, orthognathic or orthopedic treatment. Purposive sampling technique was used to select participants for the study. Posteroanterior Radiographs were taken with teeth in centric occlusion and lips at rest position. Fourteen skeletal and dental linear measurements were determined on each radiograph. The ANOVA and Independent t-test were undertaken to analyze the data.

Results: There was no statistically significant difference between dental measurements, among different age groups. Eight of ten skeletal measurements showed significant difference in both genders, but no differences were found within different age groups. The Iranians PA radiograph norms were different from those of other nations.

Conclusion: Iranian PA radiograph norms are unique and should be incorporated in orthodontic treatment plan for Iranian patients.
